PERPETUAL CALENDAR.

Application mea April 21,1920. serial No. 375,477.

T 0 all whom t may concern.'

Be it known that I, MALVTN LIGHTER, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Perpetual Calendars, of which the following is a full,

clear, and exact description.

My invention relates Ato perpetual calendars, my more particular purpose being to provide a calendar of this general type, having such form as to render it easily constructed of cardboard or heavy paper, and

so arranged as to enable the operator yto readily, quickly and accurately change the calendar so as to bring aboutthe requisite alterations peculiar to dili'erent months of the year as shown upon the calendar.

More particularly stated, I seek to make a cardboard calendar consisting of two cards, one being a wall card of large size and the other being an anchor card of smaller size, to be supported by the wall card and adjustable relatively thereto at the will of the operator, the anchor card being provided with legends indicating the aggregate days of dierent months, and so arranged that by a slight shifting movement ofthe anchor card relative lto the wallrcard, the changes desired in the calendar, incidental to the change in time from one month to the v I "slots Y9, 10, ldisposed substantially parallel with each other, as indicated in Figure 1,

next succeeding month, are easily accomplished.

My invention further contemplates an anchor card used in association with the wall card and provided with a minimum number of legends for indicating in the aggregate, the number of days in different months of the year; the idea being that the' anchor card displays a number of legends greater than the days of anyone month and yet considerably less than the number of days .of an entire year-the anchor' card serving, however, to indicate the days of slot'11 ofthe form shown in Figure 1 and each and every month in the entire year, allowance being made,4 of `course, for the fact that the anchor card isadjustable relatively to the `wall card as above stated.

My invention further contemplates various improvements, of a more or less'mechan# ical nature, in calendars of the general type,

above-mentioned.

Reference is made to the accompanying drawings forming a part of this specification, and in which like characters of referseveral figures.

ence indicate like parts, throughout the Figure 1 is provedwall card.

Figure 4 is a front elevationl of my calendar complete and shows how the operator adjusts the anchor card relatively to the yvall card, or removes the anchor card thererom.

Figure 6 is a section on the line 6-6 of Figure 5, looking in the directionvindicated by the arrows.

Figure 7 is a fragmentary rear elevation of themechanism shown in Figure 1, the anchor card, however, occupying a di'erent position', from that indicated in Figure 5.

In the form of my device appearing in Figures 1 to 4 inclusive, the wall card is i shown at 5, and is provided with display panels 6, 7, 8.

and spaced apart by a distance rather less than one-h'alf'of the-total Width of-thecard.

end -accordingtoF-igur'e 1. The slots 9, 10 are convenientlyl designated asfanchor slots, forl the reason that by their aid another card,

hereinafter described is supported by the wall card and anchored thereto.

The wall card is further provided with a These display panels are merely enclosed spaces which may be used l 'for purposes of advertising,l or in which scribed. The wall card vis also provided with a rpanel 14 rin which are printed the abbreviations of the months of the year, as well 'as' theA number of days of ,the respective months. Just below this panel, and .im` mediatelyy adjacent to` upper ends of the anchor slots 9, 10, are legendsindicating the days of the week.

The 'anchor 'card is' shown' at 15, and is 90 The slots 9,' 10 are provided with vV-shaped portions 12, 13,- orin other words, are so cutl 'that each slot tapers ofto zero lat its bottomis held firmly in position relativelyftol the.

In order to draw the anchor card taut across the face of the Wall card, as indicated in Eigure 5kthe rear end portions 27, 27b are grasped by the operator and pulled rather tightly at ,the rear of the Wall card. This done the panels 26 act somewhat after the manner of buckleftongues as. may be understood from Figure 6, and by so doing effectively secu-re the anchor card firmly in position upon the Wall card.

Iny order to shift theanchorcard relative'lyi to the Wall card, incidental to the changein time .from one inonthto another, .the operato-rfT merely shifts the anchor. card 27 slightly"` 'upward and grasping theone or the other.'` Y `of the two rear portionsofthe anchor card,

so pulls upon the same y.as to displace thel anchorfcard tothef'required extent. This .donehe shiftsthe anchor card slightly dofvvn-` Ward, into. its lowermost position. With .either form ofvmy device,

desired. At the end shifts the anchorcard as above described,

provided it needs any shifting, and in manyA instances it does not. y It Willbe noted that of each month theloperator vvhile fthe anchor card has a larger number .of legends than the days.`
